Hi Bruce, I've uploaded a tar file called umali_fieldsign_swirl.
It contains two directories one anatomical and the other retinotopy both from the same subject 29: ld29 which contains the recon-all output anatomical data sj29 which contains all the retinotopy data. the subjectfilename says ld29
The fieldsign map on the flattened patch has some out-of-plane swirls.
Is it from incorrect cuts or something else?
Thanks. Michelle

Hi Michelle,
the odd shaped shards and triangles usually means you recreated the surfaces after flattening, so the flattening needs to be redone. The swirls can be a number of things, possibly incorrect cuts. If you want to upload an example I'll take a look.
cheers Bruce

Dear freesurfers,
I've been analyzing my retinotopy , have finally been able to run fieldsign-sess without running into dimension mismatch errors.
Everything seemed ok until I tried looking at the fieldsign maps on flat patches. Some patches are warped with odd out of plane swirls. In others, all i get are odd shaped shards and triangles.
What might be the cause?
thanks, Michelle
